GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent No. 282,847, dated August7,1883.

Application tiled May 9, 1888A (No model.)

Z'o all whom it may concern:

Be it known that I, ALBERT C. CONNER, a citizen of the United States,and a resident of Richmond, in the county of Wayne and State of Indiana,have invented certain new and useful Improvements in Grain-Drills, ofwhich the following is a specification.

My invention relates to improvements in grain-drills.

' One of the objects of my invention is to provide a rock-shaft in frontof the main axle, to which the drag-bars are attached by an auxiliaryarm and a spring-connection on said arm in such a manner that the hoeson the drag-bars are controlled by the position of the Another object ofmy invention is to provide an improved spring anchor connection forconnecting the drag-bars to'the lifting-bar.

2c, f Another object of my invention is to provide suitable means forthrowing the machine into and out of gear by an attachment connectingthe intermediate gear with the rockbar placed on the frame in front ofthe sup,- porting-wheels.

Other obj ects of my invention will be fully set forth in thedescription of the accompanying drawings, in which- Figure 1 is a brokenperspective view of a Fig. 2 is a detail broken perspective view of theseeddropper, driving-gear, the ro-ek-bar, and operating devices, showingthe-rock-bar in the position for elevating the drag-bars and hoes.

Fig. 3 is a similar view'of the same parts,

showing the rock-bar in position for the operation of drag-bars andhoes. Fig. 4 is a detail transverse section of the rock-bar and itsoperating crank-arm, iiexible spring, and link,

4o showing the parts in'position for the drag-bars and hoes above theground. p Fig. 5 is a similar view of the same parts, but showing themin position pressing the drag-bars and hoes into the ground. Fig. 6 is aplan view of the 4 5 devices shown in Fig. 5, omitting the r ockbar.

A A represent rails of the main frame; B, the supporting-wheels; a, theaxle; C, the hoes; D, the drag-bars, which are hinged to the front 5orail of the main frame; or they may be hinged to shifting-bars, ifdesired.

| E represents a rock-bar j ournaled to the side rails of frame A, infront of the axle a. y

F represents a hinge-plate rigidly secured to rock-shaft E by flange b cand bolt d.

c c represent ears cast on and with plate'F.

H represents a swinging auxiliary arm hinged to the ears of plate F bybolt g.

I represents a link pivoted at one end to drag-bar D, and at the. otherend to arm H. 6o

K represents a spring coiled around sleeve A, i on arm H, one end ofwhich spring is secured in a notched lug, L, xed in arm H, and the otherend of coil-spring K projects forward on ledge f on plate F, so that thelifting of arm H upward compresses the spring, as shown 1n Fig.. 5.

m represents a stop cast on arm I-I, which strikes against flange b onbar E, to limit the. downward movement of arm H when bar E is 7o rockedforward.

M represents a segmental gear. secured to rock-bar E, and meshing withsegment N, attached to lock-lever O, which is jonrnaled to a plate, O.

P represents notches in the face of segmentplate O.

Q is a lock-bolt7 which engages with notches R is a spring-arm forwithdrawing bolt Q. 8o

By these devices the rock-bar E is readily moved and locked in anydesired position, an thus controls ythe set of the hoes. S represents aslotted bracket rigidly secured to bar E at the end opposite thelever'O. 8 5 p represents a slot pierced in bracket S concentric withthe axis of bar E.

r represents a slot connecting with slot p, but eccentric thereto. 4 l Trepresents a crank journaled to the rail 9o A; t, a crank-pin working inslots p r. T represents a link pivoted at one end to crank T, and at theother to fork-lever S', which is journaled on the shaft a:

1, Figs. 2 and 3, represents the driving-gear 95 keyed to shaft a. 2represents a transmitting-gear keyed to a shaft which journals in slot Zin the outer end of arm S.

3 represents 'the gear keyed to the shaft of 10c l the revolvingseeders.

The arrangement of parts shown 1n Figs. 2

, is rocked up and down.

and 3 is for the purpose of throwing the machine out of gear as the hoesare raised by the crank-bar E, and to throw it into gear when the hoesare lowered to the ground. This is accomplished by means of slot 9",crank T, link T, crank-arm S, and intermediate gear, 2, which is movedto and from gear 3 as bar E Stop p is concentric with the plane ofrevolution of bar E, so that a limited movement of bar E with the' hoesin the ground will not move the crank T and gear 2; but as soon as barEis moved enough to lift the hoes out of the ground, gear 2 is thrownout of mesh with gear 3 and the seeding-wheels are stopped.

The 'mode of operation is as follows: The spring K is adjusted so Ythatwhen hoes C are inthe ground the spring exerts sufficient pressure tohold them down to their work. If it is desired to force the hoes deeperin theground, the operator moves lever O forward and locks it inposition. The hoes are thus limited in their upward movement, exceptwhen a sufficient pressure is applied to overcome theresistaneev of thespring, which would readily yield in case either one of the hoes shouldstrike aresistance inthe ground-such as a root or stone-when it wouldrise and pass over a small obstruction, each hoe and its drag-bar,spring, and arm being independent of the other in such cases; but theyare controlled in unison at all times by a movement of the rock=bar E.When it is desired to raise the hoes out of the ground, the operatorreleases the lock on lever O and pulls it backward, which moves rock-barE forward, when the shoulders M on arms H strike against the fiange f onbar E, which causes the arms H, link Q, and drag-bars D to move and hoesC to be raised out of the ground by the movement of bar E, and at thesame time the gear 2 is thrown out of mesh with gear 3, and the seedingis stopped. By this means of combining the rock-bar E and arm H andlinks I with the drag-bars D and hoes C the depth which hoes C willenter the lever O are located a ,sufficient distance in.

front of axle A to allow the operator to sit on Athe frame and controlthe operation of the hoes.

The gears l 2 3 are shown as located inside of the frame; but it isobvious that they could be located on the outside of the frame by theaddition of an outside crank fixed on the saine journal as crank T, towhich the forward end of link T would be pivoted.

I claim- 1. In a grain-drill, the combination of the rock-bar E with thehinge-plate F, arms H,

link I, and drag-bars D, for regulating the hoes C, substantially asherein set forth.

and r, the crank T, having a pin working in the slotted plate, thegear-wheels for driving the seeding devices, connecting devices betweenthe said crank and one of the movable gear-wheels, and a lever formoving the rocking bar to simultaneously lift the drag-bars and throwthe gear-wheels out of mesh, substantially as described. f

3. The combination of the rock-bar E, the auxiliary arms H, the springsK, arranged on said arms, the drag-bars D, connected with the arms, theslotted plate S, secured to one end of the rock-bar, the crank T, havinga pin working in the slotted plate, the lever-arm S', journaled on ashaft, a, and carrying a powertransmitting gear-wheel, 2, a link, T',connecting the lever-arm with the crank, and a lock-lever, O, for movingand holding the rockbar, substantially as described.

4. The combination of the rock-bar E, the

auxiliary arms H, connected therewith, and having sleeves i, the springK, coiled on said sleeve, and having its ends acting, respectively, onthe rock-bar and the arm, the drag-bars D, connected with the auxiliaryarms, and a lever for rocking the bar for holding the hoes in the groundby a yielding pressure and simultaneously lifting them fronr the ground,substantially as described. 5. In a grain-drill having the rock-bar E,the hinge-plate F and lever-arm H, in combination with the coiled springK, for connecting said parts together, substantially as herein setforth.

6. The combination of the rock-bar E, the

vplate F, secured thereto, and having a stop flange, b, the auxiliaryarm H, hinged at one end to said plate, and having a stop, m, thedrag-bar D, connected with the auxiliary arm, andthe spring K, arrangedon .a sleeve of the arm and adapted to be compressed by the risingmovement of the said arm, substantially as described.

7. In combination with the drag-bars of a grain-drill, the rock-bar E,having the auxiliary arms H hingedvthereto, and connected to thedrag-bar by means of a link,with a springconnection of the arm to therock-bar, for controlling the operation of the hoes by the rockbar,substantially as herein set forth.

In testimony whereof I have hereunto set my hand.
